Abstract:
A camera module structure (100) of the present invention is arranged such that a heat-sensitive camera module (2) is joined to a printed wiring board (1) through solder joint sections (3). The printed wiring board (1) has through holes (11) formed therein and terminals (12) formed thereon so as to close front surface apertures which are formed by the through holes (11) in the mounting surface of the printed wiring board (1). The solder joint sections (3) are provided on the terminals (12), respectively. The solder joint sections (3) are formed by heating by light (heat rays) applied to the rear side of the printed wiring board (1) by way of the terminals (12) on the printed wiring board (1), so that heat is not transmitted to the camera module (2). Accordingly, the camera module structure (100) mounted on the printed wiring board (1) is realized without heat damage to the heat-sensitive camera module (2).
Abstract:
A method of producing a land grid array (LGA) interposer structure, including an electrically insulating carrier plane, and at least one interposer mounted on a first surface of said carrier plane. The interposer possesses a hemi-toroidal configuration in transverse cros s-section and is constituted of a dielectric elastomeric material. At least one sidewall of the interposer is slitted to facilitate the venting of gases and pressure therethrough. A plurality of electrically-conductive elements are arranged about the surface of the at least one hemi-toroidal interposer and extend radically inwardly and downwardly from an uppermost end thereof into electrical contact with at least one component located on an opposite side of the electrically insulating carrier plane.
